And as CNN grimly reports, "with bitterly cold temperatures and frigid waters, the chances of finding more survivors appeared to dim early Wednesday as about two dozen people remain missing."

At least 11 people from among about 4,200 who were on board died after Friday's accident. The ship struck rocks off the coast of Tuscany, took on water and tipped over on its starboard side.

As we reported Tuesday, the ship's captain is under house arrest and stands accused of manslaughter. Italian Coast Guard officers suspect he abandoned ship before all passengers were accounted for — and there's a recording of a dramatic phone call in which one of those Coast Guard officers orders the captain to return to the stricken ship.
